IMPROVEMENT m SPLICE-PIECES Foe RAiLwAv RAILS.

Specification forming part of Letters Patent No. 124,856, dated March19, 1872.

Specification describing certain Improve ments in Connecting Rails forTramways, invented by CLINTON ROOSEVELT, of the city of New York, in theState of New York.

My invention has for its object connecting the ends of the rails fortramways by springs attached to the ends of the-rails, and so formed asto keep a perfect connection under all the changes that may occur in theexpansion or contraction of the rails by the changes in temperature towhich they may be exposed.

To enable others skilled in the art of connecting rails for railwaypurposes, reference is made to the drawing forming a part of thisspecification- Figure 1 thereof showing the joint, with the upperportion of the rail cut away so as to exhibit the position and mode ofconnecting the curved spring-strap B. Fig. 2 is a side elevation of theends of two rails joined. Fig. 3 exhibits the circular spring 0, boltedor riveted on the under ends of the rails, and thereby joined, so as toallow'for the expansions and contractions of the rails by heat or cold.Fig. 4 exhibits a cross-cut section, with the spring 0 reversed from theshowing of Fig. 2.

The principle of this invention is to make the spring-strap B so astoelongate in cold weather, and to make a shorter curve in warm weather;and the circular spring 0 so as to be oblong in the line of the rails inwinter and transversely oblong in hot weather by expansion of the rails,and yet holding the ends of the rails at all times firmly in position,and answering, at the same time, the purposes of a railroad chair.

It is contemplated to use the spring 0 alone or in connection with thecurved strap B.

What I claim is- The spring 0, for connecting the ends of the rails andalso serving as a chair, substantially as herein set forth.
